Thanks for the follow-up!

I would start by checking Cyclomondo inventory for decals, but there were of course several different models and vintages and these are not the most common bike out there.

I'm starting with the project bike pictured below for my first Olmo ownership experience. I won't be doing a repaint though.

As for your bike's details, I noticed the unusual rims, which are likely original.
I believe these are a particularly narrow model of Nisi clincher rim, and one which requires extra effort to get the tire beads fitted.
As such, allow extra time when tire refitment is needed. And use the widest tubes that will still fit within the chosen tires, since narrow rims often leave the tube rubber surrounding the valve stem unable to readily fall into the rim cavity, leading to tears in the tube adjacent to the valve stem where the thinner rubber bulges into the rim cavity upon inflation. Always start with the valve stem pushed up into the tire, then give it a tug as the first few psi of inflation is initiated (to fully seat the thick rubber pad surrounding the valve stem into the rim cavity)!
This is a repeat of my frequent recommendation to use widest-possible tubes when relatively wider tires are mounted on the narrowest rims, and to tug on the valve as inflation begins.
